CAIRO (AP) — Authorities outlined plans Friday to break up two sit-ins by supporters of deposed President Mohammed Morsi, saying they would set up a cordon around the protest sites, and riot police used tear gas to disperse demonstrators threatening a TV complex.

Morsi backers also showed their defiance by briefly setting up a third camp near the airport, but later folded their tents and left.

The military-backed interim government seeks to end a political stalemate that has paralyzed Egypt and deeply divided the country. Supporters of Morsi and his Muslim Brotherhood say they will not disperse until he is returned to power.
